Popis:	1. The values of the integral intensities\(A_{C = C}^{0 \cdot 5} \) of the bands of the stretching vibrations of the vinyl groups in the IR spectra of the 1-vinylazoles are connected linearly with the π-electronic polarity of these groups. 2. The double bond has predominantly the s-cis orientation relative to the N2 or N3 atom of the heterocycle. 3. From the experimental values of\(A_{C = C}^{0 \cdot 5} \) the resonance constants\(\sigma _R^ \circ \) of the azole rings have been calculated.
